ible hose which has one end secured to the dis-V charge pipe of the pumpand which has a nozzle on its other end. Usually, the fluid outlet ofthe pump is adjacent the upper end thereof and there is a hook, also atthe upper end of the pump, for receiving Vthe nozzle. With the pump idleand the nozzle supported on its hook, the effective length of the hoseis limited to that which will support the lowest end of the loop thereinabove the surface of the concrete platform on which the pump is mounted.

In many cases this length of hose is not sufficient for adequatelyservicing all cars and trucks which may come into the station. This isdue to the fact that the tank openings of cars and trucks vary widely intheir location and also because the cars and trucks are sometimes drivenin on one side of the island on which pumps are placed and sometimes onthe other. It will be apparent that it is very desirable to have themaximum length of hose available for a pump of this nature.

In connection with new dispensing equipment, the hose is sometimesmounted on a reel within the pump and can thus be drawn out to anydesired length. While an arrangement of this type is satisfactory fornew equipment, it has the disadvantage of being very expensive anddiicult to install in old equipment.

The primary object of the present invention is the provision of a meansfor effectively increasing the length of a hose on a dispensing pump andaccomplishing this without the use of reels, counter-weighted rollers,and similar devices within the dispensing pump proper.

Another object of this invention is the provision of a means forincreasing the elective length of a ho'se for a dispensing pump in whichthe means is associated directly with the hose itself.

A still further object of this invention is the provision of a means forincreasing the eiective length of ahose for a. dispensing pump in whichthe said means substantially prevents the hose from being dragged acrossthe ground which would abrade the surface thereof and cause undue wearthereon.

These and other objects and advantages will become more apparent uponreference to the following` description taken in connection with theaccompanying drawings in which:

Figure 1 is a side elevational view of a dispensing pump having a hosethereon constructed according to this invention;

Figure 2 is a front view ofthe dispensing pump illustrated in Figure 1;

Figure 3 is a, sectional view through the hose and is indicated by theline 3 3 on Figure 1;

Figure 4 is a viewshowing the construction of the spring memberassociated with the hose;

Figure 5 is a view similar to Figure 3 but showing the spring membermounted on the opposite side of the liose;

Figure 6 is a cross sectional view of a hose according to this inventionshowing a plurality of spring members mounted thereon; and

Figure 7 is a view similar to Figure 6 but showing the surface of thehose uted or serrated in order to give it a good gripping surface.

Referring to the drawings, the dispensing pump is indicated in Figures 1and 2 by the numeral ID, and this pump includes a discharge fitting I2adjacent its top edge to which is secured a dispensing hose I4. Theother end of the hose I4 has connected thereto the usual type dispensingnozzle I6 and a hook I8 is provided on the pump for supporting the saidnozzle when not in use. This construction for the dispensing pump issubstantially standard.

In order to increase the effective length of the hose I4 it hangs on thepump when not in use with a loop therein as indicated at 20 in Figures land 2. The loop as shown comprises one and a half convolutions of thehose and under normal circumstances this is suflicient additionallength, but it will be understood that there could be additionalconvolutions in the loop if desired in order to add still further to theeffective length of the hose.

According to this invention the loop 20 in the hose is provided for bymeans associated with the hose itself. In this manner this invention canbe applied either to new or existing equipment and without the necessityof altering the dispensing pump itself in any manner.

The means which are associated with the hose and which cause it to hangin the loop as shown is illustrated in Figures 3 and 4. Reference tothese gures will reveal that the hose has associated therewith aplurality of longitudinally extending spring wires 22. These wires arenormally bent to about the shape of the loop 20 and serve to pull thehose into that shape when there is no tension exerted on the said hose.

The wires 22 are suiciently strong, taken in multiple as shown, fordrawing the hose into the loop but at the same time are sumcientlyyielding that the hose can easily be pulled out for servicing a car asindicated by the dotted out line at 24 in Figure 1.

As will be seen in Figure 4 the wires 22 lay parallel with each otherand are spaced apart and are formed into a lattice work by cross bars 26which overlie the spring wires and are secured thereto as by welding,soldering, twisting together, or some other manner of making an integralconnection.

By so binding together the wires 22 the ends thereof are prevented fromdigging into the rubber of the hose but at the same time fullflexibility of the spring member is retained for permitting the hose tobe extended to service a car.

As will be seen in Figure 3 the spring members are preferably imbeddedin a crescent shaped rubber like part 28 which is applied to the rubberlike hose I4 and bonded thereto as by Vulcanizing.

In practice, the hose can first be formed by building up on a mandreland then partially cured. Thereafter, the spring member is combined withits crescent like rubber carrier and assembled with the partially curedhose. Thereafter the entire unit may be wrapped and vulcanized accordingto the usual procedures in the art.

Figure 3 illustrates the spring member as extending around the innerpart of the loop in the hose. The length of the spring part will be suchthat it will be extended at least around the loop 20 and part way alongthe straight portion of the hose at either end of the loop. However, itmay be desirable for the spring member to extend from end to end of thehose and in such case it can also be used for grounding the hose nozzle.

The spring member can also be mounted around the outside of the loop 20as indicated at 30 in Figure 5. The arrangement of Figure 5 is otherwiseidentical with that of Figure 3.

In certain instances wherein the hose is particularly heavy there may bea spring member mounted on each side of the hose as indicated at 32 inFigure 6. While Figure 6 shows the spring members mounted inside andoutside the loop in,the hose it will be apparent that they could bedisplaced 90 degrees so as to lie on either side of the loop in thehose.

The characteristics of the surface of the hose in any of the foregoingmodifications can be modified in order to provide for a good gripthereon by fluting or serrating such surface as indicated by the numeral34 in Figure 7. Such iluting or serrating could be formed in thecrescent shaped carrier for the spring part prior to its vulcanizationon the hose, or could be formed on the hose during vulcanization, or cutthereon afterward.

In any case, this invention provides for a simple means for increasingthe effective length of the hose. The hose construction arrived at isrelatively simple and inexpensive and has long life due to the fact thatthe spring member is directly bonded to the hose and has its end partsprotected to prevent them from abrading any part of the hose.

This invention is adapted for being applied to either old or newequipment and therefore involves the minimum of trouble and expense ineffecting a conversion. Due to the resilient nature of the spring memberor members associated with the hose, no diiilculty is experienced instretching the hose out its full length, but at the same time there issuicient strength in the spring members that it will normally maintainthe hose above the ground level and thereby prevent undue wear orabrasion thereof.

It will be understood that this invention is susceptible to modificationin order to adapt it to dierent usages and conditions and, accordingly,it is desired to comprehend such modifications within this invention asmay fall within the scope of the appended claims.
